Question

решите пример 557+90*1\4 во 2 степени

Answer 1

557 + 90 * $\frac{1}{4}^{2}$ = $\frac{4501}{4}$

1) $\frac{1}{4}$ * $\frac{1}{4}$ = $\frac{1}{16}$

2) 90 * $\frac{1}{16}$ = $\frac{90}{1}$ * $\frac{1}{16}$ = $\frac{90}{16}$ = $\frac{45}{8}$

3) 557 + $\frac{45}{8}$ = $\frac{557}{1}$ + $\frac{45}{8}$ = $\frac{4456}{8}$ + $\frac{45}{8}$ = $\frac{4501}{4}$
